Hippocampal and Cortical Neurons Oscillate

In dynamic neuronal networks, pervasive oscillatory activity is usually explained by pointing to pacemaking elements that synchronize and drive the network. Recently, however, scientists at The Weizmann Institute of Science in Israel studied synchronized periodic bursting that emerged spontaneously in a network of in vitro rat hippocampus and cortex neurons, finding that roughly 60% of all active neurons were self-sustained oscillators when disconnected from the network – and that each neuron oscillated at its own frequency, which is controlled by the neuron's excitability.

[9] Physicists are expected to play a vital role in this research, and already have an impressive record of developing new tools for neuroscience. From two-photon microscopy to magneto-encephalography, we can now record activity from individual synapses to entire brains in unprecedented detail. But physicists can do more than simply provide tools for data collection. [8] Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness. The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner.

Antimatter and Antimemories

One the most intriguing physics discoveries of the last century was the existence of antimatter, material that exists as the "mirror image" of subatomic particles of matter, such as electrons, protons and quarks, but with the opposite charge. Antimatter deepened our understanding of our universe and the laws of physics, and now the same idea is being proposed to explain something equally mysterious: memory.

In a series of papers, Luc Montagnier and his group reported various effects of electromagnetic fields to DNA. It has been shown that genetic information can be transmitted to water through applications of electromagnetic field. These experiments seem to confirm what have been done by Peter Gariaev and his group in the past 3 decades, i.e. that DNA has wave character. Of course, non-particle view of DNA challenges standard paradigm of DNA and biology. The purpose of this paper is to review shortly such a non-particle view of DNA. To conclude, then we consider an extension of known adage: “Omne vivum ex vivo”, to become “Omne vivum ex vivo via crebritudo” (crebritudo is the Latin word for “frequency”).

Relation of Physiological Variables and Health

Authors:Feng LinComments: 16 Pages. mathematical and system science method is used to study biological system

Based on the non-equilibrium thermodynamics point of view that a biological system is sustained by a local potential provided by stable entropy production, we construct a mathematical model to describe the metabolism of human body system. According to the stable and periodic property of human body system, the embryonic form of the model is constructed by dimensional analysis. Based on the mathematical model, stability analysis is used to discuss the response to perturbation which corresponds to the influence on human health. With the help of physiology and medical science, the parameters in the model are determined by empirical formulas in physiology. The correspondence of parameters and the observable variables such as body temperature, body weight, heart rate etc is found out. As an example, an interesting result obtained from our model is that overweight adults, even though healthy in the medical examination reports, faces the risk of being sick, because overweight decreases the metabolic frequency, however, it drives the human body system "farther" from equilibrium (death). This result shows that the body weight of over weighted ones will gradually increase rather than staying at a stable interval. Our method provides a new approach of predicting human health according to the observable vital signs.

Once Again on the Eqilibrium Stability of a Man

The given paper studies conditions of the equilibrium stability of a cylinder – shaped homogeneous body. Thus, conditions of the equilibrium stability of different proportion upright standing men were studied. A new method allowing determination of a man’s common center of gravity was developed. An optimal bending forward angle at which the degree of the equilibrium stability of an upright standing man reaches its maximum value was determined. Hence, the appropriate conclusions were drawn.
